There is a large number of URLs - over 350 million. The site has the hosting history for domains in com/net/org/biz/info/mobi/asia back to 2000. The people who use it find it useful. I've got the bandwidth throttled though as I am moving it to a bigger server with better connectivity. However I was considering limiting Googlebot on the new server.
